A meteorologist on Fox Weather explains what "ridge riders" are, powerful storm complexes that strike the same places repeatedly in summer. He details how a strong area of high pressure, or a "bubble dome" of hot and stable air, parks itself across the South, causing day after day of hot, nasty, muggy weather with little to no rain. This high-pressure ridge also causes storms to "ride" its periphery, leading to recurring severe weather in certain areas.
